Özet

The effects of supersaturation level, sodium chloride (NaCl) as impurity, and the suspension density of the crystallizer content on the crystallization kinetics of ammonium perchlorate (AP) were studied in a mixed-suspension mixed-product removal crystallizer. The product crystals have a plate-like morphology. The crystal size distribution is not affected by the supersaturation level. There was a deviation from the ideal population density where the growth rate of pure AP crystallization was size dependent with the order of 0.4 according to Abegg, Stevens and Larson (ASL) model, However, the ASL model was not found to be suitable to express the growth rate of the crystals in NaCl containing AP solution. Also when suspension density of the crystallizer increased, secondary nucleation was observed. (C) 2000 Elsevier Science B.V. All rights reserved.
